TEST POSITIONING

The client lies prone and the therapist stands with the thumb or hypothenar eminence (specifically the pisiform) over the spinous process of a lumbar vertebra.

ACTION

Apply a downward "springing" force through the spinous process of each vertebra to assess posterior-anterior motion.

This action should be repeated for each transverse process to assess rotary motion.

POSITIVE FINDING

Increases or decreases in motion at one vertebra compared to another are indicative of hypermobility or hypomobility, respectively.

CONSIDERATIONS & COMMENTS

Rotational accessory movement can be compared at each level by performing this test to the transverse process on each side of one vertebral level.
